Every family uses tape because it's not used so often. As a result, most of the tape used at home is put for two or three years. Even if the time is relatively long, there is nothing wrong with the use.
Does the tape have no shelf life?
Everything has a shelf life! Tape is no exception. It's only used for non durable consumer goods. Generally, we don't mention the shelf life. No one will buy it back and store it for a few years.
How long is the standard shelf life of adhesive tape?
Generally, the shelf life of adhesive tape is 18 months. However, as long as it is properly stored, it doesn't matter for a long time, which is mainly related to the composition of the tape. Good sealing transparent tape can be used for 18 months under normal temperature (below 40 ℃), constant humidity (below 70% RH), ventilation and avoiding direct sunlight. It is suggested that the shelf life of adhesive tape stored at room temperature is 18 months. It is suggested that industrial factories should not stock too much tape, which will greatly lose its performance, especially viscosity. There is no need to worry about the shelf life of household tape. Generally, the requirement for stickiness is not so high, so the over guaranteed tape can be used safely.
What determines the shelf life of adhesive tape?
1. The quality of adhesive is the first to bear the brunt. High quality pure butyl ester process is used. Generally, it can be stored for more than 5 years. However, most manufacturers add a large amount of resin and tackifier to the glue (the tape is dark yellow and green). This kind of tape can only be stored for about half a year.
2. Preservation environment of adhesive tape. Temperature and humidity are the main factors, so basically, the shelf life given by all tape manufacturers must be based on the premise of normal temperature and dry environment, followed by the variety and quality of adhesives when purchasing.
